'Lightning speed': Supersonic civilian flights in US skies take another step toward swift return

• Supersonic aircraft travel at Mach 1 or faster (770+ mph), compared to conventional airliners flying 550-600 mph, potentially reducing travel times significantly
• New 'Mach cutoff' flight technique uses aircraft design, atmospheric conditions, speed and altitude to bend sonic booms upward into the atmosphere, minimizing ground-level noise impact
• The FAA plans to finalize both the in-flight noise standard and landing/takeoff noise rules by mid-2027, while also coordinating with international regulators for global supersonic flight frameworks

Summary: U.S. Moves Toward Restoring Supersonic Civilian Flights

Key Development:

The Department of Transportation announced Tuesday that U.S. regulators are advancing rules to permit supersonic civilian flights over the continental United States, ending a decades-long ban imposed due to sonic boom concerns.

Regulatory Timeline:

The FAA proposed a noise-based certification standard for supersonic aircraft and plans to introduce landing/takeoff noise standards later this year. Both rules are targeted for finalization by mid-2027.

Technical Details:

• Supersonic aircraft fly at speeds at or above Mach 1 (approximately 770 mph)
• Commercial airliners typically cruise at 550-600 mph
• New "Mach cutoff" flight technique uses aircraft design, atmospheric conditions, speed, and altitude to redirect sonic booms upward, significantly reducing ground-level impact

Companies and Leadership:

Boom Supersonic CEO Blake Scholl appeared on Fox Business, discussing the company's "boomless technology" and private funding. The company aims to launch passenger flights by decade's end.

Policy Context:

Transportation Secretary Sean Duffy characterized the move as "unleashing American innovation" and ushering in a "Golden Age of Travel." President Trump signed an executive order last year directing the FAA to establish international safety agreements for supersonic aircraft operations.

Market Implications:

The regulatory framework enables aircraft manufacturers to finalize designs and bring supersonic commercial aircraft to market. The FAA is also coordinating with international regulators to develop frameworks for global supersonic routes, potentially creating significant opportunities in the aerospace and commercial aviation sectors.
